Sin is not to be considered a light matter. In other words, it is not to be mocked. Only a fool would demonstrate this kind of behaviour toward sin.
There are two categories of sin: sins against God and sins against man. By default, every sin is against God. Yet, not all sin is against man.
Most people view sin as a private or earthy matter. Yet, every sin is against the Lord. In truth, men can sin against the Father, the Son, and the Spirit.
Sin and those who participate therein anger Lord. In the days of Noah, sin grieved the Lord so badly that it repented God that he had made man on the earth.
Rebellion is identified in a variety of ways, but the Lord often associates it to someone with a stiff neck. Society should find this concept easily grasped. A stiff neck impedes the head from bowing. Moses directly associated the stiff neck with rebellion when he said, “For I know thy rebellion, and thy stiff neck” (Deuteronomy 31:27). Like Moses, the Lord identified the rebellion of the children of Israel when He stated that they were “a stiffnecked people” (Exodus 32:9). Isaiah likewise attested to this truth by stating that rebellious people had a neck of iron sinew and a brow of brass (Isaiah 48:4). These descriptive terms demonstrate that rebellion is exemplified by an individual who refuses to bow and allow the mind to be changed. He has an unyielding spirit.
As it is with all sin, rebellion originates within the heart. Long before it manifests itself in the individual’s actions, it finds life by taking root within his heart. The Lord described a rebellious generation by saying that they were “a generation that set not their heart aright, and whose spirit was not stedfast with God.” A man with a wicked heart and the wrong spirit cannot enjoy sweet fellowship with the Lord. As rebellion takes root in his heart, the rebellion pushes out the desires for prayer and for God’s word. Humility is crowded out because of pride and self-will to the extent that a man justifies, perhaps even with scripture, his rebellious spirit. His once soft heart becomes hardened because of the deceitfulness of sin.
